PIR intrusion detector. 0.5 (1.8feet) to 12m (40feet)

GLD-235-12 is a type of digital & microprocessor-control PIR detector. With pet-immunity function. It adopt precise columnar Fresnel lens to increase the effeciency of energy receiving to achieve high sensitivity without false alarm. With high sensitivity during the detection distance: 0.5m (1.8feet) to 12m (40feet).
Advanced pet-immunity function. This detector adopt temperature compensation technoogy, can recognize the temperature of the environment and compensate IR signal accurately. Fit for indoor use.
